AUTOINJECTOR WITH AN INNER PLUNGER WHICH DISENGAGES THE OUTER PLUNGER TO RETRACT THE SYRINGE CARRIER
Publication number: 20180093046Abstract: Described is an autoinjector comprising a case, a chassis slidably arranged in the case, a syringe carrier operably coupled to the chassis, an outer plunger selectively engaged to the chassis, an inner plunger selectively engaged to the outer plunger, and a drive spring applying a biasing force to the outer plunger. The biasing force is applied to the inner plunger when the inner plunger is engaged to the outer plunger. Rotation of the chassis causes the inner plunger to rotate relative to the outer plunger and disengage the outer plunger to remove the biasing force from the drive spring on the inner plunger. When the inner plunger disengages the outer plunger, the biasing force of the drive spring pushes the chassis to retract the syringe carrier relative to the case.Type: ApplicationFiled: November 22, 2017Publication date: April 5, 2018Inventors: Yannick Hourmand, Simon Brereton, Thomas Mark Kemp, Rosie Burnell, Matthew Ekman -

Publication number: 20170326298Abstract: According to the invention, an auto-injector for administering a dose of a liquid medicament (M) comprises of a substantially cylindrical housing arranged to contain a pre-filled syringe filled with the medicament (M), a needle shroud slibably arranged with respect to the housing and adapted to rest on the skin of a patient receiving an injection, a releasable drive means arranged within the housing that is capable of, upon release, translating the needle shroud in a proximal direction (P) towards a safe position (PS) and a rotating collar rotatably arranged within the housing. The needle shroud in the safe position (PS) surrounds the injection needle after the injection has been carried out. The rotating collar engages the needle shroud in a manner that forces the rotating collar to rotate within the housing when the needle shroud is translated in the proximal direction (P).Type: ApplicationFiled: August 4, 2017Publication date: November 16, 2017Inventors: Yannick Hourmand, Timothy Donald Barrow-Williams, Matthew Ekman
